About this study

Official title: Impact of Double Stimulation (DuoStim) in Women Affected by Low Prognosis to Assisted Reproductive Technologies

The main objective of this study is to compare the cumulative ongoing pregnancy rates of two different IVF protocols in women candidate for ART characterized by low prognosis.

Read the detailed description

The patients will be allocated into two groups: control and study group _ In study group, patients will be treated by DuoStim protocol: The first phase of ovarian stimulation is started on the second day or third day of period. GnRH agonist will be used to trigger when at least two follicles ≥ 17 mm. Approximately 36 hours later, oocytes will be retrieved vaginally under ultrasound monitoring and ICSI will be performed. Five days later after oocyte retrieval, the second stimulation will be started. All embryos will be cryopreserved.

_ In control group, patients will be treated with antagonist protocol: The cycle of ovarian stimulation is started on the second day or third day of period. hCG will be used to trigger when at least two follicles ≥ 17 mm. Approximately 36 hours later, oocytes will be retrieved vaginally under ultrasound monitoring and ICSI will be performed. If serum progesterone on the day of trigger ≥ 1.5 ng/ml, all embryos will be cryostored; otherwise, fresh embryos will be transferred.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • double stimulationProcedure or surgery

    Also called DuoStim

    the patients will be treated with two consecutive ovarian stimulations in one cycle

  • conventional ovarian stimulationProcedure or surgery

    the patients will be treated with one conventional ovarian stimulation in one cycle

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cumulative Ongoing pregnancy rate

    calculated by the number of ongoing pregnancy patients divided by the total number of patients in appropriate group

    Measured: week 11 - 14 of pregnancy

Secondary outcomes (6)
  1. Pregnancy rate

    beta-hCG test is positive

    Measured: 2 weeks after embryo transfer

  2. Ongoing pregnancy rate

    defined as the pregnancy completed 11 - 14 weeks of gestation and having vital fetus

    Measured: week 11 - 14 of pregnancy

  3. Number of oocytes retrieved

    Number of oocytes retrieved identified by the embryologists

    Measured: 4 hours after occyte pick-up

  4. Number of mature oocytes

    Number of mature oocytes identified by the embryologists

    Measured: 4 hours after oocyte pick-up

  5. Number of competent embryos

    Number of embryos that can be transferred

    Measured: 3 days to 5 days after oocyte pick-up

  6. Fertilization rate

    number of fertilized oocyted divided by number of mature oocytes

    Measured: 1 to 3 days after oocyte pick-up
